Researchers Wednesday revealed that formaldehyde exposure may increase a personâ€™s risk of Lou Gehrig’s disease. One large study examined a possible link between the disease and a dozen types of chemicals. Although no significant link turned up with most chemicals, those regularly exposed to formaldehyde were 34 percent more likely to develop Lou Gehrig’s disease.

Marc Weisskopf, a researcher online casino at the Harvard School of Public Health, recently presented his findings at a meeting of the American Academy of Neurology in Chicago, saying more research will need to be done. The study involved more than 1,100 people enrolled in a cancer prevention study who died of Lou Gehrig’s disease. They were asked about their exposure to formaldehyde and other chemicals in 1982, and then followed for 15 years.

Weisskopf said some jobs have a higher risk for formaldehyde exposure, including beautician, pharmacist, mortician, chemist, lab technician, dentist, fireman, photographer, printer, nurse, doctor and veterinarian. These folks are at a 30% higher risk, according to Weisskopfâ€™s research.
